METHOD AND APPARATUS FOR KNEE JOINT FLEXIBILITY REHABILITATION
CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims priority to U.S. Provisional Patent Application
61/950,276 entitled “Method and Apparatus for Knee Joint Flexibility Rehabilitation” and filed March 10, 2014.
FIELD [0002] The disclosed method and apparatus generally relate to physical therapy for knee joints.
BACKGROUND [0003] The anatomy of a knee joint consists of three bones. These three specific bones are the femur (thighbone), the tibia (shinbone) and the patella (kneecap). The patella is located in front of the knee joint, and provides partial protection for the anterior portion of the knee. Typically, bones are connected to other bones through 15 ligaments. Specifically, the knee joint has four ligaments functioning as resilient elastic cables linking the femur and tibia together for the purpose of maintaining knee joint stability.
[0004] Collateral ligaments are located vertically on opposed parallel sides of the knee joint. The medial collateral ligament is located on the outer inside of the knee 20 joint, and links the femur and tibia. The lateral collateral ligament is located on the outer outside of the knee joint, and also links the femur and tibia. The purpose of the collateral ligaments is towards controlling knee joint sideways motion, thus fortifying the knee joint against unusual movement.
[0005] Cruciate ligaments are located inside of the knee joint, and cross each other in the general form of an X. the anterior cruciate ligament is located in front, behind the patella, and the posterior cruciate ligament is located in the back, linking the
2017258838 18 Apr 2019 femur and tibia and having a purpose towards controlling anterior and posterior movement of the knee joint.
[0006] Upon completion of knee joint surgery or other type of knee joint treatment, such as knee joint replacement or replacement or repair of any tom or damaged previously described ligaments, bone fracture and bone fracture surgery, or internal fixation surgery, or for treatment of arthritic conditions, or meniscus repair, or for knee injury recovery, regaining normal knee joint flexibility, range of motion and strength typically requires a physical therapy rehabilitation program.
[0007] Following knee surgery, or arthritic treatment, or injury treatment, or other procedure or course of treatment for the knee joint, physical therapy may be beneficially applied to restoring full and painless motion of the knee joint, along with re-establishing associated ligament and muscle suppleness. Restoration may be followed by a knee joint strengthening program focused on regaining normal function of the knee joint. A physical therapy program progressively stretches muscle(s) and tendon(s) to their former flexibility. A final rehabilitation phase encourages complete return of normal knee joint functionality.
[0008] There remains a need for an apparatus and method for knee joint gravityassist passive flexion.
SUMMARY [0009] A knee joint flexibility rehabilitation apparatus may comprise a tubular main strut having a main strut foot configured for engaging a patient support surface, the tubular main strut forming a first aperture; a bracket attached to the tubular main strut; a height-adjustment bar translatably and rotatably disposed in the tubular main strut, the height-adjustment bar having a diameter, the height adjustment bar forming a plurality of second apertures extending through the diameter of the height-adjustment bar; a knee-joint support bar fixed substantially perpendicularly to the height-adjustment bar, the knee-joint support bar being configured to receive a knee joint posterior; a support strut pivotably connected to the bracket, the support strut having a support strut foot configured for
2017258838 18 Apr 2019 engaging the patient support surface, the support strut pivotable away from a position in which the support strut is parallel to the tubular main strut to a position in which the support strut forms an acute angle with respect to the tubular main strut; and a pin removably disposable in a first orientation in one of the plurality of second apertures to fix the height5 adjustment bar against translation in one direction but permit rotation of the heightadjustment bar with respect to the tubular main strut when the knee joint posterior is disposed on the knee-joint support bar, and removably disposable in a second orientation in the first aperture and one of the plurality of second apertures to fix the height-adjustment bar against rotation and translation with respect to the tubular main strut when the knee joint posterior is disposed on the knee-joint support bar. The pin may be further removably disposed in the first orientation in one of the plurality of second apertures to fix the heightadjustment bar against translation in one direction but permit rotation of the heightadjustment bar with respect to the tubular main strut, or removably disposed in the second orientation in first aperture and one of the plurality of second apertures to fix the height15 adjustment bar against rotation and translation with respect to the tubular main strut. .

[0048] With reference now to the drawings, a novel and unique apparatus for knee joint flexibility and rehabilitation will be more fully disclosed. Such an apparatus, 10 and method of using such apparatus, may meet one or more of the foregoing objectives.
Fig. 1 provides a perspective view of an embodiment of such an apparatus. The apparatus may have a supple pad 1 encompassing nearly the full length of a knee posterior support bar 2, but not necessarily in full circumference; having said pad 1 feasibly detained, by some form of bonding agent (e.g., glue, double-sided tape, stitching, Velcro, or some other commercially available attachment means) or simply by friction or mechanical pressure. The knee posterior support bar may be substantially horizontally oriented. The bar 2 and a linearly travelling adjustable rod 3 may be mechanically joined. Said linearly travelling rod 3 may contain one or more holes 4 which may be used to lock the rod 3 in vertical position with a pin 5 or any other suitable locking mechanism.
[0049] A sliding bar strut tube 6 may serve as a structural support component affixed to horizontal strut support tube foot 7, for example, at mid span juncture 8, or at an end of the support tube foot 7. Said strut tube 6 may also serve as the housing in which said sliding rod or bar 3 may translate a determined linear distance, upon having 25 said sliding rod 3 inserted into said tube housing 6 at induction point 9. Finally, the sliding bar strut tube housing 6 may have affixed thereto a multi-task bracket 10. The bracket 10 may be located below said induction point 9, such as at reference point 11, and may be disposed at angle to strut support tube foot 7.
[0050] Said rod 3 may freely rotate in said strut tube 6. In some embodiments,
2017258838 18 Apr 2019 the rod 3 may be fixed against rotation by inserting the pin 5 through a hole 18 in the strut tube 6 and further inserted into one of the holes 4 aligned therewith. Such fixation may further prevent translation of the rod 3.
[0051] The pivotal support strut tube 12 may serve as a structural support member affixed to horizontal strut support tube foot 13, such as at mid-span juncture 14. The opposite end of said strut tube 12 may be introduced into the accommodating landing 15 of said bracket 10. Such introduction may be fixed or pivotable. A pivotable introduction may be accommodated by a pivot point, such as provision of a pivot pin inserted, indicated by reference 16. Thereby having the two collaborate opposing horizontal strut support tube feet 7 & 12 spread apart, utilizing the indicated pivot point 16, to where the pivotal support strut tube 12 engages the multi-task bracket 10 at intended engagement landing point 15, may provide a stable, rigid, gravity assisted passive flexion knee joint flexibility rehabilitation posterior support apparatus.
[0052] Fig. 2 illustrates two exemplary vertical positions of the support bar 2.
An exemplary method of using the apparatus of Fig. 1 is described in connection with discussion of Figs. 2 and 3. A recovering patient 30 may be placed in a supine position atop a physical therapy treatment table 32, or other such firm stable surface, whereby the patient may optionally bend the non-rehabilitating leg at an upward directed 45 degree angle with their foot flatly placed or may optionally have the non- rehabilitating leg resting at full horizontal extension. Thereupon, introducing the apparatus for knee joint flexibility rehabilitation, being approximately centered beneath the recovering knee 34 posterior 36; whereby the strut support tube foot 7 may impinge upon or be disposed on the table adjacent the patient's buttock(s) 38; whereby the compilation of the sliding bar strut tube housing 6 and the linearly traveling adjustable sliding rod 3 may slightly engage the back of the patient’s lower thigh 40; whereby encouraging the lower leg thigh to mimic the compilation's acute angle. The patient's recovering knee joint 34 posterior 36 may then rest upon the horizontal knee posterior support bar 2, having the desired height of said support bar 2 established. Accommodating a desired height of said support bar 2 may be accomplished by removing locking pin 5, thus
2017258838 18 Apr 2019 affording said sliding rod 3 free linear movement 17 in either an ascending or descending direction. Reengagement of the locking pin 5 may be accomplished by aligning rod 3 hole 4 with support 6 hole 18 and inserting said locking pin 5. Of course, if both of a patient’s knee joints require rehabilitation, two such apparatuses may be advantageously used at the same time. In other embodiments, the support bar 2 may be of a length sufficient to support both of a patient’s knee joints, and more than one rod 3 and more than one strut tube 6 may be used to support a single support bar, or more than one support bars 2 in an apparatus.
[0053] Should free rotating motion of the sliding rod 3 be desired, the locking pin 5 may be inserted in the appropriate hole 4 of rod 3 above support ring 19, whereby the vertical load of the patient’s leg may be transmitted through the locking pin 5 to the top of the support ring 19. The linearly traveling adjustable sliding rod 3 being so disposed, the knee posterior support bar 2 may be temporarily in parallel with opposing horizontal strut support tube feet 7 & 13, respectively. The patient's lower leg 42 may now be extended out over the horizontal knee posterior support bar 2, whereby said support bar 2 may serve as a fulcrum. The compilation engagement of the pivot support strut tube 12, and sliding bar strut tube housing 6 multi-task bracket 10; utilizing a pivot pin, referenced as 16, may have said strut tube 12 in cantilever; thereby establishing an acute angle support structure. Further, considering a phantom centerline 20 commencing from the center of the knee posterior support bar 2 end 21; traveling vertically downward ceasing imaginarily between the opposing horizontal strut support tube feet 7 & 13, simulating opposing right angles having said centerline 20 as the adjacent; revealing said tube foot 13 opposite angle line 22 extends further forward than does opposite angle line 23 of said tube 7. Having this acute triangle configuration may beneficially negate any forward catapulting or pitching effect that could be realized during gravity assisted passive flexion of a knee joint. Now, again, referencing Fig. 1 one may compare the length of the horizontal knee posterior support bar 2 to the length of the horizontal strut support tube feet 7 & 13, the length of the horizontal strut support tube feet 7 & 13 being equivalent or longer so as to reduce any involuntary lateral or
2017258838 18 Apr 2019 rolling movement of the horizontal knee posterior support bar 2.
[0054] Continuing on with Fig. 4 being an exploded illustration of the embodiment of Fig. 1, an end cap 24 may be inserted into each end of supports 7 and 13 respectively. The strut and support tubes, rods and/or bars may comprise any suitable cross-sectional configuration, such as round, square, polygonal, channel, angular or the like. The feet may comprise tubular, angular, channel or plate structural members.
[0055] The foregoing thus describes a new knee joint flexibility rehabilitation apparatus. The knee joint flexibility rehabilitation apparatus maybe specifically intended for gravity assisted passive flexion of the knee joint. The knee joint flexibility 10 rehabilitation apparatus may be used to provide knee rehabilitation treatment specific for knee joint stiffness, flexibility and strengthening. The knee joint flexibility rehabilitation may be used to provide knee rehabilitation treatment specific for swelling reduction, pain reduction, spasm reduction, and compression reduction. The knee joint flexibility rehabilitation apparatus may be used to provide knee rehabilitation treatment 15 specific for injury recovery, arthritic relief therapy, bone fracture recovery and surgery recovery. The knee joint flexibility rehabilitation apparatus may provide an arrangement that is appropriate for and contently supports the posterior intersection relationship of the femur and tibia of a post-operative recovering knee joint. The knee joint flexibility rehabilitation apparatus may promote deliberate gravity assist passive 20 flexion specific towards gradual knee joint decompression and muscular and tendon stretching.
